A portable power station has a battery that is rechargeable either by solar panels or through a vehicles 12 volt outlet or when you plug it into the house.
Once the battery of the portable power station is charged it will provide you with 110 volt electrical power through the regular electrical outlets.
The battery powered outlet is basically a battery with an inverter built in that converts the 12 volts of the battery into 110 volts to power 110 volt appliances and devices.
However the portable power station will only provide 110 volt power for as long as the battery stays charged but using a solar panel to keep the battery charging can help keep the 110 volts flowing.
You can also setup solar panels on other batteries and use an external 110 volt or even 220 volt inverter to get regular electrical power.
Another option is to use an inverter in your vehicle and while your vehicle is running it will provide electrical power through a 110 volt outlet.
After you shut the vehicle off though you should unplug the inverter or turn the inverter off so it doesn't draw your battery down.
